Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Unauthenticated Cross Site Scripting (XSS) in JetFormBuilder <= 3.6.0.1 versions.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

An unauthenticated cross-site scripting (XSS) vulnerability exists in JetFormBuilder plugin versions 3.6.0.1 and below. The vulnerability allows attackers to inject malicious JavaScript code through form inputs that are not properly sanitized before being rendered in the application's output.

MitigationUpdate JetFormBuilder to a version newer than 3.6.0.1. If immediate updating is not possible, disable the plugin until a patch can be applied.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify JetFormBuilder plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'JetFormBuilder' in the list, or check the wp-content/plugins/jetformbuilder directory exists
    Affected if JetFormBuilder is present in the plugins directory
  2. Check installed JetFormBuilder version
    Navigate to Plugins > Installed Plugins > JetFormBuilder and read the version number displayed under the plugin name, or inspect the main plugin file header for the Version field
    Affected if The version is 3.6.0.1 or lower
  3. Confirm JetFormBuilder forms are in use
    Go to JetFormBuilder > Forms in the WordPress admin panel and verify that at least one form exists and is published
    Affected if Active forms exist and are embedded on the site
  4. Check if form submissions are displayed publicly
    Review the site's published pages and posts that contain JetFormBuilder forms to see if submitted data is rendered back to users (such as in submission confirmations, user dashboards, or frontend submission displays)
    Affected if Form submissions or user input are rendered to visitors without server-side output encoding

You are affected if JetFormBuilder version 3.6.0.1 or below is installed AND your site publishes forms that display user-submitted data to visitors.

Generated from the published advisory. Verify against your own configuration.

Check your environment
